CARDlNGv-MACHINE.

PEC'IPICATION forming part of Letters Patent No. 301,193, dated July 1,1884.

Application filed November 22, 1882.

1 and State of Massachusetts, have invented a new and useful Improvementin Carding-Ma chines, of which the following is a specification.

My invention relates to carding-machines, and more particularly to thatclass illustrated in Letters Patent No. 265,901, granted to me October10, 1882; and the invention consists, first, in a means for raising thesmooth roller away from the needle-roller without removing it from themachine; secondly, in a concave shield having a knife-edge, arrangedbetween the needle-roller and the feed-rollers, for the purpose ofremoving the fiber from the needleroller, so as to insure the deliveryof all the fiber to the feed-rollers; thirdly, in the arrangement of aseries of saw-teeth bars in connection with a receptacle or box overeach tooth. I

Referring to the accompanying drawings, Figure 1 is a longitudinalvertical section of a carding machine embodying my improvements. Fig. 2is an enlarged view in detail of the device for elevating the smoothroller. Fig. 3 is an enlarged view in detail of the breaker-roll,showing the position of the sawteeth and dirt-receptacles. Fig. 4 is anenlarged view of the sawteeth.

The general construction of the machine is similar to that shown anddescribed in the patent above referred to, and requires no fur therparticular description here, it being understood that the devicesemployed to actuate the several parts of the machineare substantiallythe same as shown in the patent granted to me October 10, 1882, No.265,901, A being the lap-roller; O, the smooth roller; D, the

. needle-roller; 'G- G, the feed-rollers; H, the

breaker-roll; I, the discharging-roll; J, the carrier-roll, and K thelicker-in. P and Q are the workers and strippers; V, the doffer; 7c, thedoffer-eomb, and Z Z are calender-ro1ls'.

a a are lever-arms fulcrumed on the axis of the needle-roller D-one armat each en d-as shown. I

To the ends of the longer arms a a is journaled the smooth roller 0, andthe ends of the (N0 model.)

shorter arms a a are connected together by a rod or bar, I).

To the rod 1) is connected a rod, 0, which extends back, and is providedwith a handle, (Z, projecting from the rear of the machine. WVhen a newlap is to be introduced into the machine for the action of theneedle-roller and its accessories, the bar or rod 0 is drawn out, whichpulls do W11 the arms a a and raises the longer arms a a and removes theroller O away from the needle-roller, as shown by the dotted lines. whenthe lap is properly placed, the rod c is pushed back and the roller 0resumes its position. I thus obviate the necessity of removing theroller 0 from the machine, as

required in the machine above referred to in across the machine.

On the upper end of the shield e is a metal knife-edge, f, which isplaced very near the ends of the needles or points of the needleroller,and serves to remove the fiber from said needleroller, so as to insurethe delivery of all the fiber from the same.

A little to the rear of the upper part of the breaker-roll H is arrangeda series of sawteeth bars, N, as seen in Fig. 4. These bars are made intwo parts, which are separated longitudinally and joined together, sothat the teeth of one part shall be opposite the spaces between theteeth of the opposite part. The saw-teeth bars are similar to thoseshown in my former patent, above referred to, and the object of placingthem as shown is to more effectually aid in clearing the fiber of seedsand other extraneous matter which are deposited in receptacles h 72placed over the said saw-teeth bars, and which are thus prevented fromagain returning to the fiber. At the front of the machine are thecalender-rolls Z Z, to which the sliver is conducted.

What I claim as my invention is- 1. The combination of the roller 0, thele ver-arms a a, the needle-roller D, rod or bar I), and the rod 0,substantially as and for the purpose set forth.

2. The concave shield 0, having the knifeedge f, in combination with theneedle-roller In testimony whereof I have signed my name D andfeed-rolls G G, as and for the purpose to this specification in thepresence of two subspecified. v scribing witnesses.

3. The combination, with the breaker-r011 CHARLES EDWARD WHIIWORTH.

5 H, of the saw-teeth bars N, arranged above Witnesses:

the said breaker-r011, and the receptacles h, as J 0s. H; ADAMS, and forthe purpose described. E. PLANTA.
